Italian yacht builder Rossinavi announced the launch of the M/Y Seawolf X, a hybrid-electric power catamaran capable of cruising in full electric mode for 100 percent of the time on one-day trips.

In a press release from the company, Rossinavi announced the innovative yacht carries the BluE label designating the shipyard’s new sustainable philosophy. Seawolf X has a 140-foot length overall, 45-foot beam and is an all-aluminum vessel that combines sleek design with environmentally friendly solutions.

The press release notes that the catamaran can cruise in full-electric mode for 100 percent of the time on day trips and 90 percent of the time on multi-day trips. Rossinavi also states that the vessel is capable of making transatlantic trips while in electric mode 80 percent of the time. 

The Hibernation mode, kicking off when the power catamaran is moored, reduces consumption to a minimum and the energy generated can be given back to the dock or a private property. Rossinavi boasts that the Seawolf X supplies enough energy to charge up an entire villa. The ship’s two diesel generators can quickly recharge its batteries on shore power in five hours.

“After years of study and construction, it is now a source of satisfaction and pride for us to witness the launch of project Sea Cat, now Seawolf X, the first hybrid-electric multihull vessel,” said Rossinavi COO Federico Rossi in a press release. “This yacht showcases remarkable technological innovations in both power management and propulsion technologies, marking the beginning of a new chapter in next-generation vessels.”

Yacht of the future

Rossinavi’s BluE label hybrid-electric yachts are propelled by batteries and solar panels with the goal of reducing CO2 emissions. Energy collected by these solar panels during the day is stored in advanced batteries and released at night, creating a bioluminescent effect similar to glowing plankton.

On top of its environmental perks, Seawolf X also includes an onboard artificial intelligence system developed by Rossnavi. Rossinavi AI constantly analyzes the operation of the vessel and acts as a brain that can learn from observation and predict the needs of the guests on board. Rossinavi AI is able to talk with crew members and monitor the battery pack to keep it in a range of 20 to 80 percent –the ideal range to ensure better battery pack lifespan.

The boat’s exterior architecture is by Fulvio De Simoni Yacht Design, while New-York-based practice Meyer Davis Studio designed the interiors. The Fulvio De Simoni Yacht Design team came up with a sleek and low-profile silhouette, reminiscent of a sports car.

The yacht has three distinct spaces for outdoor living: a lively cockpit centered around a pool, a large sundeck with sunbathing and living spaces, and a bow area featuring a hidden pool and convertible home theater. The yacht design team accurately integrated solar panels into the vessel, ensuring plenty of surface space for energy recovery.

“We set out to envision the boat of the future, unbound by convention yet grounded in feasibility with cutting-edge technology for minimal environmental impact,” said Fulvio De Simoni, founder of Fulvio De Simoni Yacht Design, in a press release.
